Advanced Functional Materials, Volume 35, Issue 14, April 3, 2025.This work integrates nano‐sized cobalt control gates into a fully‐depleted silicon‐on‐insulator (FDSOI) nanowire architecture, combining electrical and ferromagnetic properties for scalable electron spin qubits. The design enables quantum dot formation at cryogenic temperatures and localized electric dipole spin resonance (EDSR).

Chiral degeneracies and Fermi-surface Chern numbers in bcc Fe [PDF]
, 2015 The degeneracies in the spinor bandstructure of bcc Fe are studied from first principles. We find numerous isolated band touchings carrying chiral charges of magnitude one (Weyl points) or two (double-Weyl nodes), as well as nonchiral degeneracy loops ...

Observation of Chiral Fermions with a Large Topological Charge and Associated Fermi-Arc Surface States in CoSi. [PDF]
Physical Review Letters, 2018 Topological semimetals materialize a new state of quantum matter where massless fermions protected by a specific crystal symmetry host exotic quantum phenomena.

Advanced Functional Materials, EarlyView.The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...

Fermi Surface of the Most Dilute Superconductor
Physical Review X, 2013 The origin of superconductivity in bulk SrTiO_{3} is a mystery since the nonmonotonous variation of the critical transition with carrier concentration defies the expectations of the crudest version of the BCS theory. Here, employing the Nernst effect, an

Topological Dirac semimetal BaAuSb
Physical Review Research, 2023 Dirac semimetals feature Dirac cones with topologically nontrivial states in the bulk that are protected by crystalline symmetries. They attract considerable attention due to rich quantum states and properties of interest, such as high Fermi velocities ...

The low-temperature collapse of the Fermi surface and phase transitions in correlated Fermi systems [PDF]
arXiv, 2011 A topological crossover, associated with the collapse of the Fermi surface in strongly correlated Fermi systems, is examined. It is demonstrated that in these systems, the temperature domain where standard Fermi liquid results hold dramatically narrows, because the Landau regime is replaced by a classical one.

Life on the edge: a beginner’s guide to the Fermi surface
, 2016 The concept of the Fermi surface is at the very heart of our understanding of the metallic state. Displaying intricate and often complicated shapes, the Fermi surfaces of real metals are both aesthetically beautiful and subtly powerful.
